Ryan,

Thanks for your reply. Connectivity seems to have improved. This is what I see now. 

1. Is the Ethernet speed test being performed while directly connected to the main Deco node? - Did test at main node and got good speeds: 907/848
    
2. Can similar results (high download, slow upload) be replicated with other devices - including ones connected over Wi-Fi? - So this is where it gets interesting. If I stand near a node (like three feet away), be it the main or the two used as satellites I get very good wifi. Main: 397/450 , Sat 1: 488/585, Sat 2: 478/388. However as I move away from any of the nodes the upload speeds degrade much more than the download speeds. For example from various locations in house that are at least 20 feet from node or through at least one wall I get: 306/126 , 193/17 , 156/54 ,376/227, 336/122
3. Have you tried bypassing the Deco to test directly at the source and compare the results? Directly from FIOS Router I get very good speeds
    
4. Is your Internet source (e.g., modem, ONT, gateway) connected to the top, middle, or bottom port on the main Deco? Bottom
    
5. Is the main Deco connected to a modem, or to a modem + router gateway device? Connection from street is: ONT - Verizon Router (CR1000b) - TP Link Switch - Deco Main Node. I have ethernet backhauls running from all nodes.
